Nance suffered the injury during the first quarter of Tuesday’s matchup after bumping into Indiana forward Thaddeus Young while driving to the basket. He shot both free throws, but then limped off the court and eventually went into the locker room with the team’s trainer to be evaluated further.

“I just know when he was walking off the floor he was moving very, very gingerly,” coach Larry Drew said Tuesday (via cleveland.com).

Nance, who signed a four-year, $45 million contract extension in October, is averaging 8.8 points and 7.5 rebounds this season.

The Cavaliers are 8-34 and have been riddled with injuries this season, including missing star Kevin Love with a nagging foot injury.
